Technical Field

The invention relates to a container type integrated system for combustion treatment of garbage, and belongs to the technical field of environment-friendly treatment of garbage.

Background

In the process of urbanization, garbage is once a burden for urban development as a product of urban metabolism, and many cities in the world have the situation of surrounding garbage. With the increasing emphasis on environmental issues, energy conservation and environmental protection have become the subject of development in various countries, and have begun to provide industrial development opportunities for garbage disposal. The annual growth rate of garbage all over the world is 8.42 percent, and the growth rate of Chinese garbage reaches more than 10 percent. Worldwide, 4.9 million tons of garbage are produced each year, and only China produces nearly 1.5 million tons of municipal garbage each year. The accumulated quantity of domestic garbage in China reaches 70 hundred million tons. Under such tremendous waste pressures, it is reasonable to believe that the waste disposal industry will become the star industry in the future.

At present, two main methods of garbage disposal are landfill and incineration. Although the landfill cost is low, the landfill garbage is not subjected to harmless treatment, and a large amount of bacteria and viruses remain; hidden troubles such as heavy metal pollution of the methane and the like are hidden; the garbage leakage liquid can pollute underground water resources for a long time, so the method has potential great harm and can bring endless future troubles to descendants. The method not only does not realize the resource treatment of the garbage, but also occupies a large amount of land, which is a dangerous practice of reserving pollution sources to descendants. Landfill is prohibited in many developed countries at present. The competent departments at all levels of the government of China gradually know the problems of the treatment technology and tend to forbid and eliminate the behaviors.

The waste incineration mode has higher environmental protection requirements on ash and tail gas, and further can only make a large article on the combustion efficiency and tail gas purification efficiency of the incinerator. Therefore, most of the current garbage incinerators meeting the environmental protection requirements are equipped with incinerators and tail gas purification devices with complex structures. And most of the installations of burning furnace and tail gas cleanup unit need more civil engineering structure to support, and not only the place occupies greatly, and the installation is complicated moreover, and difficult whole transportation removes, all needs on-the-spot installation and debugging basically, is difficult for popularizing and applying.

Disclosure of Invention

The invention aims to provide a container type integrated system for combustion treatment of garbage. The garbage incinerator can efficiently and harmlessly treat garbage, has a compact integral structure, can be transported as a whole, has no requirement on soil construction, does not need field installation, can reduce the installation cost, is easy to popularize and apply, and is particularly suitable for small and medium-scale garbage combustion treatment plants.

The technical scheme of the invention is as follows: the container type garbage combustion treatment integrated system is characterized in that: the garbage bin comprises an upper container body and a lower container body which are connected in an up-and-down laminated manner, wherein a garbage feeding assembly, a combustion furnace assembly, a quenching heat exchanger and a bag-type dust collector are sequentially arranged in the upper container body from front to back; the lower container body is internally provided with a filtrate tank below the garbage feeding assembly, a cooling water tank and an ash slag tank below the combustion furnace assembly, and a dust collecting box below the bag-type dust remover in sequence from front to back.

In the above container type integrated system for combustion and treatment of garbage, the garbage feeding assembly, the combustion furnace assembly and the quenching heat exchanger are located on one side of the upper container body, the tail gas multistage treatment tank and the auxiliary gasification furnace (for example, waste wood chips and fuel gas are generated by pyrolyzing high-calorific-value garbage) are sequentially arranged on the other side of the upper container body from back to front, the lower end of the tail gas multistage treatment tank extends into the lower container body, and an alkaline liquid pool (for example, sodium hydroxide solution sprayed by a desulfurization tank used in the tail gas multistage treatment tank) located below the auxiliary gasification furnace is arranged in the lower container body.

In the container type integrated system for combustion and treatment of garbage, the activated carbon absorption tower is arranged between the quenching heat exchanger and the bag-type dust remover and used for primary absorption of harmful gases in tail gas, activated carbon dust which is easily brought out from the activated carbon absorption tower can be removed in the bag-type dust remover, and the treatment pressure of a subsequent tail gas multistage treatment tank can be greatly reduced.
